GRAPHITE BLOCK
Production introduce
The main physical and chemical properties of graphite blocks have reached: compressive strength 125MPa, a Shore hardness of 65 degrees, the resistivity 12μΩm. Producing more than 800mm diameter, particle size less than 18 microns large-sized enterprise isostatic graphite products, leads the large size of graphite products, to meet the needs and improve the domestic and other isostatic graphite products share.
